Clone Performance

Feb 2025–Jul 2026 · vs SPY

Hypothetical growth of cloning every reported 13F position and rebalancing on each filing, indexed to the same start.

Cloned portfolio
+13.5%
SPY
+24.4%
Annualised alpha
-7.4%
Max drawdown
−16.9%

Estimate. 13F holdings are quarter-lagged and long-only, so the clone rebalances about 45 days after each period end — when the filing becomes public — and excludes options and short positions. Past performance does not predict future results.
